96 yr old w/muscle invasive bladder cancer

Does the hospital provide psyco-concology service to cancer patients?
Psyco-oncologist is psychologist specializing in cancer and cancer patients.

A while ago, I watched a video interview by a psyco-oncologist (sorry I cannot find it now). One of his case
was a female patient who did not want to have a chemotherapy. The psyco-oncologist evaluated
the patient and determined the the patient had depression. So, he prescribed anti-depression
drug. Sometime later, the patient came back told the psyco-oncologist that she was going to
have the chemotherapy in rather up-beat mood.

my 92 year old father was presented with this option. He has aggressive invasive bladder cancer. He is reluctant to go for regular infusions and very worried what a PET scan would reveal. Which he would have to do regularly. He just is tired and not into any of this . It's hard. I understand where he is coming from.

My 96 year old father in law was diagnosed in January 2019 w/ muscle invasive bladder cancer and decided on no treatment. He subsequently agreed to radiation but only had 2 treatments. He had another cystoscopy 3 months ago that showed bladder cancer in situ. Another cysto was done this week and today biopsy results show muscle invasive bladder cancer. Surgery is not an option for his age and chemo would likely be fatal for him so his urologist is saying that he could possibly have immunotherapy. Any thoughts on this?
